The government's jobs report for February will be published on Friday. The Federal Reserve has highlighted unemployment as key in deciding how-and-when ultra-loose monetary policy will be scaled back, so the report will be scrutinized for hints as to future central-bank action.

In the meantime, investors will listen out for speeches on Thursday from Fed officials William Dudley, Charles Plosser and Dennis Lockhart.

Worried about 'unintended consequences' of QE: Fed's Plosser

Charles Plosser, president of the Federal Reserve Bank of Philadelphia, says he is worried about the "unintended consequences" of the U.S. Federal Reserve's quantitative easing program.

Plosser was interviewed on CNBC in London on Thursday. He said he was "very worried" about the risk of side effects from the Fed's massive bond purchases, and warned U.S. economic growth might never return to pre-crisis levels.

Investors will also continue to eye events in Ukraine, after Russia's bloodless invasion of Ukrainian peninsula Crimea over the weekend. European heads of states are set to meet on Thursday to discuss developments in the country.

Ukrainian boxer-turned-politician Vitali Klitschko told CNBC that Russian President Vladimir Putin was frightened of how events were unfolding in Ukraine.

"He is scared of what is happening because the [Ukrainian] people don't want to…live with this corruption, live without human rights and that is why the people want the changes," said Klitschko, who is a potential presidential candidate in Ukraine.
